A freight company employs a compressed spring to shoot packages of 2.0 kg up a 1.0m high frictionless ramp. The spring is compressed 30cm and consists of a spring constant of 500N/m.
i) Determine the speed of the package if it reaches the truck?
ii) A careless worker spills his soda on the ramp making a 50cm long sticky spot having a coefficient of Kinetic friction of 0.30. Will the subsequent package make it into the truck?
